The surface supplied diver can rely on the tender to compensate for loss of buoyancy by pulling up on the umbilical, or belaying the umbilical, allowing the diver to climb it, which may be safer if the umbilical passes over sharp edges or places where it may snag, making this a much lower risk problem than for a scuba diver.
Helmets for head protection, and head mounted lights may snag the long regulator hose which is looped around the neck and may cause difficulty changing the diving mask. [50] Head mounted lights also increase diver profile and hydrodynamic drag, and increase the risk of shining the light in the buddy's eyes when looking towards him. [50]
Surface-supplied diver at the Monterey Bay Aquarium, Monterey, California US Navy Diver using Kirby Morgan Superlight 37 diving helmet [1]. Surface-supplied diving is a mode of underwater diving using equipment supplied with breathing gas through a diver's umbilical from the surface, either from the shore or from a diving support vessel, sometimes indirectly via a diving bell.

Divers wear diver weighting systems, weight belts or weights to counteract the buoyancy of other diving equipment, such as diving suits and aluminium diving cylinders, and buoyancy of the diver. The scuba diver must be weighted sufficiently to be slightly negatively buoyant at the end of the dive when most of the breathing gas has been used ...
Slack line is an entanglement hazard, and entanglement may prevent controlled ascent if the diver cannot wind in the line effectively. Assistance may be needed to disentangle thin lines if they snag on equipment that the diver cannot see and reach, and cutting free in an emergency may leave the diver's position unmarked. [29] [30]
Bodycam footage shared by the Volusia Sheriff's Office shows officers trying to rescue a huge ocean sunfish stuck on the beach near Ponce Inlet.
